Pinarello loves to make their pro-level innovations accessible. The GAN GRS Disk follows the wheel tracks of the Dogma K8-S Disk. The K8S is the cobblestone cruiser Pinarello built for Team Sky to take on the rough roads of Paris-Roubaix and the northern classics. Geometry, aerodynamics, flex, comfort, braking have all taken lessons from that WorldTour bike. Sky’s racing game is very much about accruing small benefits to equal a big advantage, and the GRS, accrues all those benefits as well.

The GAN GRS Disk is it’s own bike. The most noteworthy departure is space for tires up to 38mm in width (32mm if you run fenders over the tires). That’s wider than is allowed in UCI-sanctioned cyclocross racing. You can really drop tire pressure with tires that big, and that much rubber on the ground means you can soak up some huge holes and some rough roads that aren’t really roads at all.

If that isn’t enough to lick your chops over, the rear end has been designed with a shock sitting atop the stays. The shock is the S of GRS, and what sets it apart from the GR. The adjustable elastomer bumper, same as the shock on the K8-S, means you have even more damping between you and the wheel. It’s a simple, telescoping elastomer shock that gives you up to 10mm of compression, which is more than enough to turn back-breaking stones into a more velvety track. And thanks to carbon, with Torayca T600 plies in the mix, the flattened chain stays offer vertical flex, that’s why they call them Flexstays, without any power-eating pivots by the bottom bracket or rear axle.

This is something special, a mixed-surface bike that still is designed to go fast. It’s not just the geometry that is racy, but the tube shaping. As with the K8S, these tubes benefit from Pinarello’s FlatBack profile down and seat tubes. The design is aero, but comfortable, as the leading edge airfoil is chopped down in back, both to improve comfort and minimize weight. The head tube, fork legs, and seatstays are also shaped for aerodynamics, but a bit less so to help the Onda shape with vertical compliance. The seat post and stem are aero as well.

The bike is set up with rotor disc brakes. The brake mounts are designed for rotors up to 160mm in diameter. The fork has a flat-mount system for the front caliper. The rear triangle has Pinarello’s RAD System for mounting the rear brake caliper. It’s a lightweight, secure means to fix the caliper to the stays without bulking the chainstay. By keeping the stay thinner, the ride is closer to that of a bike with conventional rim brakes. Keeping the lateral rigidity high as well as keeping things secure and simple are thru-axles, both front and rear. 12x100mm in front and 12x142mm in back. More secure mounting, potentially faster wheel changes.

This GAN GRS also boasts many of the cool design extras of the K8S. They feature a tapered 1 1/8” to 1 ½” steered, Think2 internal cable routing—which works with mechanical, electronic, or hydraulic systems. If you go the electronic route, the battery goes in the seatpost, though you’ll need an accessory adapter if your bike doesn’t come with electronic shifting. The bottom bracket is the reliable Italian threaded standard—easy for servicing.

The Pinarello GAN GRS Disk deploys the aerodynamics of the Dogma, adds clearance and disc brakes for rough roads, and smoothes out the ride with a shock. All these features make this bike one that never is at a loss regardless of the terrain or speed.
